SIPHON-ACTION METER CLOSET.

Application filed April 27, 1923. Serial No.' 635,131..

This inventionrelates to siphon action water closets, and it has for its primary object the provision of a closet of this character which may be cast in a minimum number of parts and which, consequently requires a minimum number of oining or sticking operations.

A further ob'ect is to H provide a method of forming siphon action closets in which the production of the tortuouscloset passageways is effected without the difficulties ordinarily encountered in or attendant upon the manufacture of such closets by preexist- 7 ing methods. 7 V I A. still further object is to simplify closet forming methods to the extent that there is effected a substantial reduction in the amount of labor involved, and to provide a method which may be carried out without the requirement for a high degree of expert knowledge of the art and without the exer- V cise of more than ordinary dexterity or skilfulness on the part of the artisan.

Another object within the contemplation of the invention is the'production of a closet bowl having an improved construction of' flushing rim.

With these and other objects in view, the invention resides in the features of construction and in the process of manufacture which will hereinafter be fully described,

reference being had to the accompanying drawings, in which- Figure 1 is a vertical longitudinal section of a siphon action closet produced-in accordancewith the invention;

Figure 17 is an enlarged section of a fragmentary portion of the bowl, illustrating the rim structure; and i Figure 18 is a similar section through the rear end of'said'bowl. 7

Referring to said drawings, A indicates taken generally the siphon action closet which is V composed of a body portion 1, a base 2 havingtherein a waste passage or drain vent 3, a bowl 4, a trap 5 separating the usual ascending and descending legs 6, and 7 of a siphon passageway leading from the interior of the bowl 4 to the and a hollow rim 8.

The bowl 4 and the lower part or half 8 of the rim 8 are cast integrally, as is shown in Figs. 12, 17 and '18, and the upper part. or half 8" of said rim,'cast separately, as shown in F igs. 151 and 16, is bonded to said waste passage 3,

lower half 8 through the 'intermediacy of a heavy slip, introducedin thei usualimanner," for producing a hollow flushing rim which is to all intents an integralstructure The upper interior surface of the bowl 4' has a fluted formation, ribs 9 alternatingwith grooves or channels being formedron said bowl. Said ribs and said channels ex tend inward horizontally fromthe interior vertical face ofnthe inner upright wall of the trough-like lower half 8 of the rim,1and thence extend downwardly along the intorior of the bowl a, as shown, said ribs being gradually reduced in depth until they wholly disappear at a suitable level below said rim. The inner tat portion the under face oi the upper halt 8 of the rests directly upon the horizontal tops of said ribs 9. tending lip 8 formed on the upper half 8* of the rim seats closely against the upper inwardly facing portions of said ribs 9 and constitutes a deflector by which flushing water passing from the interior of he rim through the passages intermediate said horizontal portions of the ribs is deflected down- I fect and improperly positioned perforations frequently encountered in closet l oval in which the innerunder sides or" t perforated manually, as ordinary, follow-i ing the molding operation,

Another objection to the formation of perforations by hand punching is that the ma' terial punched out may remain within the hollow of the rim in a position or positions seriously interfering with the How of the fwater. This objection is of course wholly obviated in the present invention, and, furthermore, smce the rim 1s cast in two parts,

as aforesaid, the walls of the latter may be I made of uniform thickness throughout, thus avoiding internal obstructions which might result in retarding or otherwise interfering with the flow of the water.

In constructing the closet, the bowl 4 and thebody 1 are molded separately, following which said parts are assembled or joined to form a practically unitary structure, as will hereinafter be described. Additionally, said body 1, together with the base 2 and the "trap ,5, ismolded in two separate parts -wh1ch are subsequently joined in the formation of the body.

Referring, first, to the body 1 method ot'lorming the same, a three-part mold is employed for molding integrally the base 2, one side'or half of the trap 5 and 'one side of the body, and a two part mold is employed for molding the other half of the trap and the opposite side of the body Forming one part of the aforesaid threepartmold is a baseB illustrated in Figs. 3

Qandy6, which is preferably of oblong oval form, andfwhich hasa flat marginal seating r1m or-ledge 10 'for'the reception An v internal downwardly eX- and the V d I I I of the lower edge portions of a pair of comple -mental-s'1de members 11 and 12. V Defining the inner edge of said marginalled' outer edge 13- of a table 13 having its level elevated slightly above that of said ledge;

and spaced inward slightly from the said e of the table 13 at one end of the la ter an elevated panel 14. Slmilarly spaced and elevatedabove said table at the opposite end of the latter is a relatively sn'ialler panel '15, herein shown as of crescent shape; and

interposed between said panels and spaced from the latter to form channels it; is a'rim l7, sail ring enclosing the upper end 01": an opening which extends through the base 3 and which isadapted toreceive therein a plug 19, shown in Fig. As will be apparent, the seated lower edge portions of the sidegmembers l1 and 12 and the elevated table 13, panels 1 1- and 15, ring 17 and plu'gg 19 so associated relatively th'at'they adapted to shape the hollowed under s i of the closet base 2, forming; therein the; drain vent or passage 3 and forming, thereon the encirclinr sin -like fian e -20fhi1d the outer supporting flange 21. Theside members ll and 12 of said three-- art mold are designed to be, supported b the mold base B in opposing complemcntal relation and, inconjunctionwith said base B, to term therebetween wholly enclosed molding space tor a side 1 of the closet bodv l and for a laterall dis osed wing 5% Y w the latter constituting one compleinental part or half of the trap 5. 'llieop-p te "internal molding spaces provided in sale.

side members are shaped to impart ,to the body wall or-side 1F the desired'contour or confi uration and the required thickness The member 12 has formedthcrein a recess or molding space'22 of the irregular "form or design required in the production of the wing and having a depth approximating one half that of the trap 5. A filler opening or hole 23 of suitable size and form is provided in the mold base illas shown.

Instead of the body forming; mold bein ef made in three parts, as, described, the base and one of the sides, 'r s the side 11, may be made integral, asshown in Fig. 6. V

The two-part mold employed in the formation of the opposite side Pot the closet body a .and the opposite half orwing' 5 otthetrap is composed of oppositeside members 2% and 25 having their confronting" internal 'faces shaped to give to the bodyfwalll" the desiredfcontour or configuration and thick-- ness -The member 24 is'fiange'd at the lower part of its inner portion to provide-a seating ledge 26 upon which the "member '25 rests. Said member 24 has formed in its inner face a recess or molding space'27 whichscorresponds in all'substantial respects to the recess 22 of the member 12 of the three-part 'mold hereinbefore"described, said recess 27 being adapted for shaping the wing 5 which, in the finished body, is joined to the top, member 29. Said base member 28 has a hollow bowl shape with its interior corresponding in contour with that desired tor the exterior of the bowl l, whereas the top member 29 comprises an upwardly removable core 29 of the approximately.invertedcone shape required for shaping the internal surfaces of the bowl walls. 7

The member 28 has an annular flange 28 surrounding its upper edge designed to receive thereon in seatedrelation a corresponding fiangeQE) formed on and surrounding the upper part of the core 29; An internal .I'abbet-like ledge 30, formed in the upper part of the walls of the base member 28, and a downwardly facing rib 31 formed onthe flange 29 of the top member 29 are adapted to conjointly give shape to the lower half 8 of the flushing rim, 8, said rib forming the channel which, in the finished article, con

ill

' in said rim.

stitutes the lower'partot the water passage The core 29 has formed around its exterior beneath' its flange 29 a successlon of regularly spaced alternate channels or flutes 8:2 and ribs or fillets designed to form the.

ribs 9 and intermediate channels oi the closet bowl 4:, the flutes 33 being adapted to have the horizontal upper ends thereof partially overhanging the ledge 30 ot' the base member 28. v 1 r The base member 28 has a channel 34 crossing the flange 29 at its rear-most part for shapingthe under side of the usual tubular supply connection? 35 of thecloset; and formed in the wall of the base member is a relatively deep vertically disposed chanv nel 87 which tGIIIllDZLtQSflh its lower end'ln v a socket-like seat 38. The core29 has an external rib-like swell 29 formed thereon which corresponds in general outlinetoand which cooperates with said channel for shapinn the bowl 4: to form inte'riorly ot the latter a vertical concave channel constituting water course or fan wash 89 through. which a large proportion of the volume offlushing water entering through the supply connection 35 is conducted directly down alone the rear wall of the bowl to the funnel-like lower bottom outlet of said bowl.

The upper part 8 of the rim 8 is formed 41 and by two complemental mold sections 7 I shaped d2 which have their confronting. faces Unc or more iillc" to give part the required configuration, aeshow lfigs. i3, l4, l5 and Ehe various mold parts heein described rim is mounted in place, the necessary amount of slip for uniting the abutting edges of the various parts being introduced in the manner well understood by those ski led in the art. The partslso assembled are then allowed to dry and are subsequently baked to completely unite the whole'in structure which, practically considered, is integral throughout. I

fAniong the various advantages possessed by the method of casting, hereinbefore described is that each of the various parts is accurately formed of a predetermined shape. proportions and dimensions and that .the

surfaces are insured the desiredregularityof contour.
